The exhaustion of fossil fuel and the greenhouse gas emission are one of the most significant energy and environmental issues, respectively. Photovoltaic (PV) generators and battery energy storage systems (BESSs) have been significantly increased for recent years. The BESSs are mainly used for smoothing active power fluctuation of the PV. In this paper, PV‒BESSs integration of two DC/DC convert...

This research analyses the operation of a solar PV powered electric vehicle charging station with energy storage that has been developed and demonstrated at the University of California – Davis, West Village, the largest planned zero-energy consumption community in the U.S. The intelligent energy management approach introduces solar PV electrical energy forecasting and EV charging demand projec...

Modern restructured power systems sometimes operate with heavily loaded lines resulting in power system to work under condition of higher power loss and higher voltage deviation, which may result in insecure operation of power system; even sometimes it may lead to voltage instability or system collapse. It is mainly due to continuous and uncertain growth and demand of electrical power. This pap...

Due to the line impedance impact on islanded low-voltage microgrids, traditional droop control cannot guarantee the proper power sharing between distributed generation (DG) units. In the meanwhile, droop control would cause voltage and frequency deviation, which will influence the power quality of customers. This paper proposed an enhanced droop control scheme with autonomous frequency restorat...

I n the early 20th century, the Dutch physiologist Willen Einthoven stated “What you or I think is not important. What is important is the truth.” Today, this concept remains pertinent to our efforts to better understand myocardial mass complexity. Einthoven’s 1906 paper “Le télécardiogramme” presented the first collection of abnormal human electrocardiograms (ECGs) using the string galvanomete...

DC voltage and Josephson Within the JRPs “Q-wave” (finished in 2016) and its successor “QuADC” (started in 2016) VSL is working on the practical and theoretical aspects of quantum waveform metrology, including generation of arbitrary Josephson signals, the deviation problem of voltage leads at higher frequencies, a Josephson delta-sigma converter, voltage scaling and uncertainty calculations. A...

This paper presents an efficient and reliable Particle Swarm Optimization (PSO) algorithm for solving Reactive power optimization including voltage deviation in Power System. Voltage deviation is the capability of a power system to maintain up to standard voltages at all buses in the system under standard conditions and under being subjected to a disturbance. Reactive power optimization is a co...
